Drawn Shell Casing Simulation

A DEFORM-2D simulation modeled the multi-station drawing and cold heading of a copper case (shell) used in an ammunition cartridge. Product: DEFORM Premier; DEFORM-2D; Forming Express (2D) Courtesy: American Ballistics Summary: SFTC worked with American Ballistics to develop an optimized cold drawing progression for a copper cartridge shell casing. The DEFORM-2D Multiple Operation environment was coupled with the DOE/Optimization Module to perform an in-depth series of process studies. The product was successfully launched, with DEFORM simulations instrumental in improving the efficiency of the development process compared to slow, costly shop trials. Case Study: Ammunition comes in many shapes and sizes, serving purposes including defense, hunting and sport. Finished forms are typically standardized to fit specific weapons and produced in high volume. Ammunition can be constructed of multiple components including a case (shell), bullet (projectile), propellant (exp
